In newly updated COVID-19 guidance on its website, the Centers for Disease Control and Prevention said that loosely woven cloth masks provide the "least protection", while masks like N95 respirators offer the highest level.

In some cases, Americans might want to opt for higher-quality masks like KN95 and N95 respirators, the agency said.

"Wearing a highly protective mask or respirator may be most important for certain higher risk situations, or by some people at increased risk for severe disease," the CDC stated.

The CDC recommendation stops short of calling on Americans to choose one mask over the other, maintaining that any mask is better than no mask.

The updated guidance comes after weeks of health experts urging Americans to upgrade their masks in the face of omicron.

The White House will launch a new website on Wednesday to distribute 500 million free at-home rapid tests that'll be mailed to Americans' doorsteps, senior administration officials said on a Friday call with reporters.

People will be able to order four tests per household at from this first batch of 500 million. The White House will also launch a call line for people who don't have computer access.

The tests will take seven to 12 days to arrive, the senior officials said.

On Thursday, President Joe Biden also pledged a second 500 million tests, bringing the total free tests that will eventually be offered to Americans up to 1 billion.

New York is "turning the corner" following record-breaking COVID-19 cases over the holidays, according to Gov. Kathy Hochul.

She said the seven-day case average and positivity rate are heading down.

One week ago there were over 90,000 daily cases, and now just 49,027 daily cases, the governor said Friday.

However, state numbers may be skewed due to the increased demand in testing during the holidays.

New York state is seeing a slight decline in hospitalizations, but at 12,000 patients, that number "is still very high," the governor noted.

In New York City, Mayor Eric Adams said Friday “it really appears” hospitalization numbers are “stabilizing.”

"Based on our optimistic views, we appear to be moving in the right direction," he said.

Nationwide, more than 157,000 COVID-19-positive patients are currently receiving care -- a pandemic high, according to federal data.

More than 5,200 children are currently hospitalized with confirmed or suspected cases of COVID-19 – also a record high.

On average, over 20,000 Americans are being admitted to the hospital with COVID-19 each day, a figure that's more than doubled over the last month, according to federal data.

It's still not clear how many of these patients were admitted to the hospital for COVID-19 and how many people coincidentally tested positive after they were admitted for other reasons.

About 83% of staffed adult ICU beds are occupied (by COVID and non-COVID patients) -- the highest ICU capacity in one year, according to federal data.

On average, the U.S. is now reporting a record high of more than 782,000 new COVID-19 cases each day, according to federal data.
